Twin-screw conveyor pump filling machine is a relatively advanced filling equipment. The following is a detailed introduction to it:
Structural composition:Twin-screw conveyor device: This is the core component, including the first screw, the second screw and the screw barrel. The first screw and the second screw are arranged in parallel and are rotatably installed in the screw barrel. The spiral structures of the two screws are intermeshed and rotate in opposite directions. The screw barrel has a feed inlet and a discharge outlet. The feed inlet is usually set on the barrel wall, and the discharge outlet is located at one end of the screw barrel. After the material enters from the feed inlet, it is conveyed to the discharge outlet under the rotational pushing action of the twin screws.
Refrigeration system (available in some models): For some filling scenarios that require controlling the material temperature, the twin-screw filling machine is equipped with a refrigeration system. The evaporator of the refrigeration system is arranged around the barrel wall of the screw barrel. Common evaporators include cooling jacket evaporators or finned evaporators sleeved on the periphery of the screw barrel. A cooling cavity is formed between the cooling jacket and the screw barrel. There are a liquid inlet and a liquid outlet in the cavity. In order to enhance the refrigeration effect, multiple partitions will be set in the cooling cavity from the liquid inlet to the liquid outlet. There are liquid passage holes on the partitions, and the liquid passage holes on adjacent partitions are staggered.
Forced feeding device (optional): Located at the feed inlet, it is used to assist the material to enter the screw barrel more smoothly and ensure a continuous and stable feeding process. Especially for materials with poor fluidity or high viscosity, the role of the forced feeding device is more obvious.
Negative pressure system (available in some models): It includes equipment such as vacuum pumps. By opening a vacuum suction po
